Man-Made Stones

These are all man made materials. Some gems such as the emerald are lab grown materials, others are merely glass faceted. Have fun with this page. Though we prefer to cut real gems, we do from time to time cut CZ, lab grown corundum etc. As we cut them, they will be added to the page.

Unless otherwise noted all materials have been faceted here at the Facet Shoppe by John or Barb.

Mt. St. Helen's Ash

This is material from the original makers who had the original patent on making gem material from Mt. St. Helen's ash which occurred in the May 18, 1980, eruption. The process involved processing the ash to remove one of the trace minerals present, and substituting another mineral in it's place to create a transparent gem material which is most often seen as rods pulled from the melted ash.

This has the same composition of the natural material, though some of it comes in shades of beautiful blue which is not found in nature as large crystals.

This is a really fancy design, with the entire crown of the stone covered with small diamond shaped facets, a design that optimizes the light return in a colored stone. This one is 10.6 mm, 5.62 cts. Priced at just $147.00

MM-223-Spinel: This one is a green/yellow spinel, faceted in an original octagon design by John. It is hard to describe this color- it is a vivid pastel green/yellow, and this exceptional design brings out the brightness and sparkle. This one is 13.9 mm, 17.42 cts. $ 249.00

Strontium titanate

It was long thought to be a wholly artificial material, until 1982 when its natural counterpart was discovered in Siberia and named tausonite.
It has extreme dispersion which creates a fabulous gem, and has been marketed as "Fabulite". It has a hardness of 5.5 - 6, so not a good stone for a ring. RI=2.41 which is about the same as a diamond, but it has very strong dispersion.

NEW! MM-326-Strontium: This one was faceted by John in his design called "Eye Strain" -
a reference to a lot of facets to create a unique appearance! This one is 13.5 mm, 19.25 cts. $ 285.00

YAG

This is similar to the chemical structure of the garnet family, so it is listed as a man-made garnet variety that has not been found in nature. This is an excellent gem for all jewelry uses.

MM-115B-YAG: Pink YAG (Yttrium Aluminum Garnet)- is one of the finest man-made gems available. It has an amazing, very saturated pink color, and a high (1.833) RI.

Faceted by John. $ 67.50
